ecology
scientific study of interactions between organisms and the environment. shows distribution and abundance of organisms
Ecologists work in a range. go big to small…
global
landscape
ecosystem
community
population
organism
organismal ecology
studies structure, physiology, and behavior
population ecology
focuses on factors affecting population size and diversity
community ecology
deals with species interactions in a community
ecosystem ecology
emphasizes energy flow and chemical cycling among biotic and abiotic components
landscape ecology
deals with abundant ecosystems and how they’re arranged in geographic regions
global ecology
examines influence of energy and materials on organisms across biosphere
climate
long term prevailing weather conditions in an area
4 major components with climate
temperature, precipitation, sunlight, wind
\
macroclimate
patterns on global, regional, and landscape level
microclimate
very fine patterns such as those encountered by a community of organisms under a fallen log
global climate patterns are determined by
Solar energy and the Earth’s movements in space
latitudinal variation
angle of sun
seasonal variation
tilt of the earth
air circulation and precipitation patterns are driven by
solar radiation near equator
terrestrial biomes characterized by
vegetation
aquatic biomes characterized by
physical environment
if tropical forests are at the equator, what is at 30 or 60 degrees
dry and arid at 30, forests at 60
impact of climate is shown with a
climograph
